ICE-CAN.

SPECIFICATION forming part of Letters Patent No. 690,312, dated December 31, 1901. Application filed January 31, 1901.` Serial No. 45,4 74. (Nomodel.) l

To cir/ZZ whom, it may concern: v

Be it known that I, CHARLES MCSHERRY, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Ice-Can, of whichthe following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure lis a side elevation of an ice-can constructed in accordance with my invention. Fig. 2 is a vertical transverse section of the same. Fig. 3 is a horizontal section, and Figs. 4, 5, and 6 are detail' views hereinafter referred to.

My invention relates to sheet-metal cans, and particularly to those whichare used for producing artificial ice; and its object is to provide a can with a smooth interior which will have no rivets upon the inside, which' can be easily shipped in a knockdown condition, and which will be strong and durable.

In the drawings I show a can which tapers slightly toward its bottom on all sides and is formed with two sides 2 2 and two ends 3 3, each of which is formed of a separate sheet. The seams at the corners of the can are formed by beading the edge of one of the sheets and rolling or crimping the edge portion ofthe other around the bead, forming a joint such as shown at 4 in Fig. 5. These joints are cut away at the top of the can for a distance at least as great as the width of a wrought-iron band 5, which rests upon the upper ends of the four corner-seams and is held in place by bending lips or flanges 6 down over it from the upper ends of the four sheets. The strengthening-band at the top of the can is thus secured in place without rivets, giving a neat top of smooth and pleasing appearance.

The bottom 7 of the can sits up within the body and has depending iianges 8, which fit against the lower endr portions of theV bodysheets and are reversely bent to inclose them, as shown at 9 in Fig. 4. The seam thus formed is securely fastened by offsetting the joint, as shown at l0 in Fig. 4, thus producing a sharp bend in this seam, which serves to hold the bottom against strains tending to force it from the body, and, moreover, reduces the amount of solder necessary and gives a closer seam. The appearance is also improved, since the reverse portion 9 of the bottom-flange is or may be substantially flush with the outer face of the sides of the body.

To further strengthen the bottom and provide rests upon which the can will stand, I provide bottom-feet or guards 11, one at each corner, and consisting, preferably, of a U- shaped metal casting having two parts extending at right angles to each other and do away with any abrupt shoulders upon the exterior.

The advantages of my invention will be apparent to the manufacturers and users of icecans. The Vrivets with countersunk heads which have heretofore been present in icecans and which held the cake are done away with,no rivets being used in the can structure. The can being made in four separate sheets or` pieces can be shipped in knockdown condition and easily assembled in the ield,where heretofore the cans, being shipped in completed form, have occupied a large amount of space, and thus made freight charges large. The use of the rolled seam at each corner greatly strengthens the can and keeps its sides from bending or buckling. The upper encircling band is securely held in place without rivets and is easily placed and secured. The feet or bottom-guards are cheap and may be easily applied. Theoffset bottom-seam holds the bottom in place and reduces the amount of solder necessary. The amount of labor in making the can is reduced, so that the can is cheaper and at the same time stronger and more durable than the present ice-can.

Each of the features of my invention con--V stitutes a separate item which may be used either with or without the other items, and I intend to cover them separately in my claims.

Many changes may be made in the size and shape of the can, as Well as in its seams, zc., without departing from myinvention.

l. An open-topped ice-can having each side formed of a separate sheet with tapering edges secured together with rolledv seams, and a strengthening-band surrounding the can near its upper end, the interior of the can being free from rivet-heads; substantially as described. v

2. An open-topped ice-can, having eachside formed of a separate sheet with their edges secured together by rolled seams, said seams being cut away at their upper ends, and a strengthening-band surrounding the top of the can and supported on the upper ends of the cut-away seams; substantially as described.

3. An ice-can having rolled corner-seams cut away at their upper ends, and an encircling band resting on the ends of said seams and secu red by bent-over edge portions at the top of the can; substantially as described.

4. An open-topped ice-can, formed of fourl tapering sheets, and having rolled seams at .its corners, and a bottom having a reflex joint with the bottom ends of the four sheets; substantially as described.

5. An ice-can havinga bottom provided with depending reversely-bent flanges which inclose the lower ends of the can sides, forming three-ply seams, the two inner plies of the seams having a horizontal jog or offset, the outer ply lying in said offset and being in substantially the plane of the side of the can su bstantially as described.

6. A open-topped ice-can ,having rolled corner-seams and lower corner-guards provided with legs extending at an angle to each other and clam ped to the lower corners, said guards.

having cut-away portions to receive the seams; substantially as described.

7. An ice-can having a bottom with depending ilanges forming a reflex joint with the sides, and angular corner-guards clamped to the corners of the said joints; substantially as described. Y 8. An ice-can having a bottom with depending flanges forming joints with the sides,'said` joints having offsets therein, and angular oorner-guards clamped to the joints and forming feet for the can; substantially as described.

9. An ice-can having rolled corner-seams with their upper end portions out away, and an encircling band around the top of the can resting upon the cut-away portlons of the my hand.
